The majority are well differentiated vascular tumors which grow slowly and have a low potential to be invasive,although malignant subtypes occur. Meningiomas have a predilection to arise from the parasagittal region,cerebral convexity,sphenoidal ridge,olfactory groove,and spinal canal. They tend to present in the fourth to sixth decades of life with signs indicative of a slowly progressive mass lesion. Specific clinical manifestations depend on the location of the tumor,but may include INTRACRANIAL HYPERTENSION,cranial neuropathies,ataxia,and other focal neurologic signs.
